Specification of Letters Patent. Patented Aug. 31, 1915.

Application filed January 26, 1915. Serial No. 4,461.

To aZZ whom t may concern.'

Be it known that I, DANIEL HARRINGTON, a citizen of the United States,and a resident of Newark, in the county of Essex and State of NewJersey, have invented a new and lmproved Switch rFie-Plate, orn whichthe following is a full, clear, and eXact description.

rThe object of the invention is to provide a new and improved switch tieplate, arranged to prevent the main rail from spreading by providing afirm support for the inner edge of the rail base and without obstructingthe free movement of the switch rail.

ln order to accomplish the desired result, use is made of a tie platehaving in its top a recess extending across the width of the plate forthe base of the rail to rest on, the inner side wall of the recess beingundercut for the reception of the inner edge of the rail base, a braceabutting against the outer face of the web of the rail vand having abase plate fitting into the outer portion of the said recess adjacentthe rail, theinner edge of the said base plate abutting Vagainst theouter edge of the rail base, and the outer edge of the said base plateyabutting against the outer side wall of thesaid recess. Use is also madeof registering spike holes in the tie plate and baseplate for thereception of a spike and registering lnotches are formed at the innercorners of the rail base and the tie plate for the passage of spikes,the heads of which engage the top of the rail base and the Shanks ofwhich abut against the outer edge of the rail base.

A practical embodiment of the invention is represented in theaccompanying drawings forming a part of this specification, in whichsimilar characters of reference indicate corresponding parts in bothviews.

Figure l is an elevation of the switch tie plate as applied and showingthe main rail in cross section on the line 1-1 of Fig. 2; and Fig. 2 isa plan view of the saine with one of the rail spikes shown in section.

@n top of the railroad tie A is placed a switch tie plate B, provided onits upper face with a recess C extending in the direction of the lengthof lthe rail D, from one edge of the tie plate B to the other edgethereof, so as to form a support for the base D of the rail D to reston. The inner side wall C of the recess C is provided with an undercutfor the reception of the inner edge of the rail base D, to hold the railbase YDie A.

down in position on the bottom of the recess C and thus prevent outwardtilting or spreading of the rail. `lll/'hen the tie plate B is extendedinwardly a distance beyond the wall C it forms a support forvthe switchrail E to slide on, it being understood that by the arrangementdescribed the switch rail E can be readily moved toward and from therail D as no'obstruction whatever' is in the way of the switch rail Eand at the same time the inner edge of the rail base D is properlysupported by the undercut wall C. The outerface of the web D2 ot' therail is engaged by a brace F provided with an integral base plate Fiitting into the outer portion of the recess C. The inner edge of thebase plate F abuts against the outer edge of the rail base D, and theouter edge of the base plate F abuts against the outer side wall C2 ofthe recess C. By the arrangement described the rail D is properly bracedand is thus held against outward movement especially as the edges of therail base D are engaged by the undercut wall C and the inner edge of thebase plate F.

The base plate F is provided adjacent the `outer end ofthe brace F witha spike hole F2 in register with a spike hole B formed in the tie plateB, and a spike Gr is driven through the said registering holes F2 and Band into the tie A to fasten the base plate F in position on the tieplate B and to fasten the latter in position on the It is understoodthat the head G of the spike G rests on top of the base plate F to holdthe latter down. The base plate F is provided at the inner corners withnotches F3 in register with notches B2 formed in the tie plate B so thatthe rail spikes H can be driven through the said registering notches F2'and B2 and into the tie A. The base H of the rail spikes H rests on topof the outer portion of the rail base D, and the Shanks of the saidspikes H abut against the outer edge of the rail base `D to assist inholding the rail D against outward shifting. By reference to Fig. 2, itwill be noticed that the spikes H are located directly opposite the endsof the undercut side wall C of the tie plate B to insure a firm holdingof the rail in place in the recess C of the tie plate B.

The inner end of the tie plate B is preferably provided with spike holesB3 to receive spikes I driven into the tie A for holding the inner endof the tie plate down on the tie A.` It is understood that the heads ofthe spikes I are out of the range of movement of the switch rail E.

A switch tie plate B, as shown and described is placed on each tie Acrossed by theswitch rail E so that the main rail vD isl properlysupported along its inner edge, and the switch rail E is free to movetoward and from the main rail on closing or opening the switch.

The switch tie plateshown and described is composed of but two parts,which can be readily assembledafter the main rail D is placed inposition in the recess C, and on spiking the switch tie plate to the tieA by the use of the spikes G and I-I the parts are fastened together. yHaving thus described my invention, I claim as new and desire to secureby. Letters Patent:

l; In a switch tie plate, a tie plate having i in its upper facea recessfor the base of the main rail to rest on, the inner side wall of therecess having'an undercut into which fits the inner edgeof the railbase, a brace i adapted to abut against the outer face of the web of themain rail, the said brace hav- I ving a base plate fitting into theouter porf forv the switch rail to slidel on, the said base plate ,andthe said tie plate having registeringl apertures, a spike passingthrough the said apertures when driven intothe railroad tie, the head ofthe spike resting on top of the base plate, the latter having notches atin its upper face a recess for the base of the main rail to rest on, theinner side wall of the recess having an undercut into which fits theinner edge of the rail base, a brace adapted to abut against the outerface of the web of the main rail, the said brace having a base platefitting into the outer portion of the said recess, the inner edge of thesaid base plate abutting against the outer edge of the said base and theouter edge of the said base plate itting the outer side wall of the saidrecess, the said tie plate being extended a distance beyond the innerside wall of the said recess to form a support for the switch rail toslide on, the said base plate and the said tie plate having registeringapertures, a spike passing through the said apertures when driven intothe railroad tie, the head of the spike resting on top of the baseplate, the latter having notches at the inner corners and the said tieplate having notches in register with the said base plate notches, andspikes engaging the said notches, the Shanks of the said spikes abuttingagainst the outer edge of the rail base and the heads of the said spikesresting on top ofthe rail base.

InV testimony whereof I have signed my name to this specification in thepresence of two 'subscribing witnesses.
